Typical engine symptoms owners report

  • Engine mounts reportedly fail early, letting the engine shift and put excess torque on the transmission, sometimes causing steering shimmy.
  • Owners describe sudden stalling while driving at moderate speeds (around 20-45 mph), sometimes with a distress warning light before the vehicle loses power.
  • Some report a rear main seal failure near 70,000 miles, noticed as oil stains and dripping under the vehicle.
  • A few owners describe the speedometer dropping to zero while the engine kept running, requiring a tow to the dealership.
  • Reports include vibration, grinding noise, or a coolant/radiator warning right before the engine stalled and needed towing.
